T 0 all whom it may concern:

Be it known that I, CYRUS A. MCCAIN, a citizen of the United States, residin at Bensonhurst, in the county of Kings, tate of New York, have invented certain new and useful Improvements in Printing-Press Inking Mechanisms, of which the following is a specification.

The present invention relates to ink ng mechanisms for flat bed cylinder printing presses in which a reciprocating type bed cooperates with an impression cylmder sultably' operated by impression mechan sm.

The principal objects of the invention are to provide inking mechanism whlch shall completely and effectively ink the form-from one'end to the other with an even film of inkupon all reciprocations of the type bed in regularoperation, and do so upon all kinds and cuts of'forms, to producea simple, durable and efficient construction, to construct and arrange theparts so that they will be readily accessible for attent1on, repair and adjustment and so that they may be readily removed and reassembled, to provide efficient means for moving inking rollers out of engaging position when not in service, in order-to prevent their deformation, to provide a novel vibratingmechanism by which both the form vibrating rollers and the ink plate vibrating rollers may have their strokes independently adju'sted .and adjusted from zero to a maximum, to provide cooperating mechanism between the cylinder tripping mechanism and the mechanism for raising partsof the inking mechanism into their out-of-service po- 'sition, and in the provision of other features,

combinations and details, all of which will be more fully understood upon reference to the following detailed description taken in connection with the accompanying drawing. Such description and drawings set forth the preferred form of my invention and the appended claims set forth lts'scope.

' In the drawing, Figure 1 is a side elevation of a fiat bed cylinder printing press embodying all. the features of the present invention; Fig. 2 is a diagram of a modified arrangement of form inking and form d stributing rollers; Fig. 3 isa deta1l plan view of the pedal footboard shown d1rectly beneath it in Fig. 1; Fig. 4 is a plan view of a sufficient portion of the press shown n Fig. 1 to illustrate both the rollers for distributing and applyingink to the form and the rollers for distributing and applying ink to the ink plate; Fig. 5 isa fragmentary plan view of the form duct roller showing the means by which it is operated; Fig. 6 is a side elevation of the press taken from the side opposite to that illustrated in Fig. 1; Fig. 7 is a fragmentary view illustrating a further portion of the press not shown in Fig. 6; Fig. 8 is a side elevation of a portion of the press illustrating the form distributing rollers raised away from the form inking rollers; Fig. 9 is a detail-elevation of aportion of the mechanism shown in Figs. 6 and 8, illustrating the manner of raising the form inking rollers into their non-service position; Fig. 10 is a detail plan .of parts illustrated in Fig. 9; Fig. 11 is an elevation of a portion of the mechanism for vibrating certain of the distributing rollers with the frame shown in section, the plane of section and the direction of the view being indicated by the. line 1111 of Fig. 6; Fig. 12 is a sectional view of parts of the mechanism shown in Fig. 11; Fig. 13 is an elevation of another portion of the vibrating mechanism with the frame shown in sectlon, the plane of section and direction of view being indicated by the line 13-13 of Fig. 6; Fig. 14 is an elevation of one of the journal boxes employed in supporting certain of the ink plate rollers, illustrating the clip by which the journal of the roller may be held raised in non-service position;

is a detail elevation of the mechanism for upon suitable guideways and is reciprocated by any suitable mechanism, preferably that illustrated in my aforesaid patent. The side frames 30 and 31- have upward extensions 35 and 36, respectively, which-are recessed' at their upper ends to receive the two-part journal boxes 37 and 38, which carry the journals of the impression cy1inder 39. The bed 34 is provided at one end with an ink'plate 40and'Tnk is supplied to said plate from a fountain 41 located at the front of the 'press, by means of a fountain duct roller 42 which is reciprocated back and forth to convey ink from the ink fountain roller 43 to the ink plate'40 and to the associated roller 44, which in turn conveys it to the ink plate roller 45. The duct roller '42 first contacts 'With roller 44 and then with both roller 44 and ink plate 40 as the latter passes under it. Thus the ink is applied directly to the ink-plate by the duct roller 42 and the ink plate roller 45. From the ink plate ink is taken up, worked, and distributed by means of the rollers 46, 47 and 48, working together as one set, and the rollers 49, 50 and 51, Working together. as another set. Of these various rollers, those designated 42, 45, 46, 48, 49 and 51 are composition rollers, and those designated.

44, 47 and 50 are steelrollers. The rollers 47 and 50 are vibrating rollers and are adapted to be actuated by the vibrating shaft 52. As the bed travels toward the impression cylinder the ink which has'been applied and distributed to the surface'of the ink plate 40, is in part taken up by the form duct roller 53 and in part by the form inking rollers 54 and 55. Preferably the duct roller 53 takes up ink from the outer end of the ink plate 40, removing it for a distance equal to the-circumference of'the roller, and the rollers 54 and .55 take up'the balance. The ink taken up by the duct roller 53 is not transferred directly to the form but to a train of distributing rollers 56, 57, 58, 59 and 60. These feed a continuous flow of Worked-up ink to the rollers 54 and 55 when passing over the form onthe print stroke, thus insuring an even color on the form. Of the several distributing rollers, the rollers 57 and 59 are steel rollers and the remainder are composition rollers; the rollers 56, and 60 are vibratory rollers, actuated from the vibrating shaft 61.

It may be pointed out that in the usual inking mechanisms of the prior art, four rollers are used. The first takes up ink from the ink plate through a distance equal to its circumference and then continues to 'ing at the point where the first roller left off. The third and fourth rollers, however, are not inked because the travel'of the plate is insufficient; As the ink plate travels in the reverse direction, thetwo first rollers deposit a good portion of their ink back on the clean table instead of holding it for the form." In'bontrast to this, in my device the outer roller 53 skips the ink on a portion of the plate and then descends to receive the ink from the outer end of the plate for a distance equal to the circumference of vthe roller, thereby leaving the balance of the ink, namely, that on the balance of the plate,

to be taken up by the'rollers: 54 and 55. In 1 this way all the ink is taken up from the ink plate and that which the roller 53 takes upgoes throu h the form distributing rollers and is fe continuously to the rollers 54 and 55. The latter, therefore, deposit upon the form not onlythe ink which they themselves have taken up but. also that which is fed to them through the distributing rollers. As a result of this construction a larger ink plate may be employed and an even color across'the sheet is insured.

It requires a greater travel. of bed and cylinder when fourrollers are used, in order to have the last roller clear the form when the type bed is on the front center. -With my device the last roller is the form du'ct roller and it does not roll onthe form; therefore I am able to reduce the sizeof the cylinder and driving gears for a. given size of sheet, thereby reducing the travel of the bed and cylinder, andtherefore increasing the number of sheets printed when main taining the same surface speed of bedand cylinder. From tests made, my device gives a much better distribution than with four rollers.

Referring to the shaft of the roller, as clearly shown in to the fountain roller 43 and its. actuating mechanism, I have prov ded the Same with a ratchet wheel 62 which 1s keyed each advance of the dog. Asthe dog recedes, it slips over the teeth without actuating the'wheel 62. A spring 64 engages the dog and causes it to engage the ratchet teeth A pivoted upon a pin 65 which extends laterally from a projection 66 upon a loosesleeve 67 mounted upon the roller shaft and permaupon its advance movement. The dog 63 is tain roller.

ciprocate in the guide frame 71 carried upon '70 and extends upward, terminating at its upper end in an angular bend 7 0 which may be seated in any one of the notches 7 0 to set thewheel 7 0" in any desired position. The wheel 7 0 also has a flange which has a peripheral cam face upon which a pin. 7 0 extending laterally from pawl 63 is adapted to ride. The position of the point 70 at which the pin 70"passes from the elevated to the depressed portion of the cam face, determines the point in the stroke of the dog 63 at which it will engage a tooth of the ratchet wheel 62. And the extent of the movement of the pawl 63 after a tooth is thus engaged, determines the extent of rotation of the fountain roller 43. Obviously the wheel 70 may be set so that the pawl 63 will not pass the point 70 and thus no engagement of a tooth be had and consequently no advance of the roller 43. Or itmay be set so as to engage a tooth at the beginning of its forward stroke and thus producea maximum advance of the fountain roller 43. Or, again, it may be set at any intermediate point with a resulting corresponding advance of the foun- The rack 70 is mounted to 'reav suitable stud 72 or other projection from the frame of the press. The rack 70 is connected to a second rack 73 by a'rod 74. The rack 73 is engaged by the teeth of a segment 75 pivoted at 76 to a portion of the frame 31. The segment 75 is oscillated by means of a connecting rod or pitman 77 which is connected to a pin 78 on the side of the gear wheel 79 which thereby acts as a crank disk. The pitman 77 is connected to the segment 75 by means of a in 7 9 which is adjustably secured in a slot 9 in the segment 75. By shifting the pin 79 toward and from the pivotal point 76, the throw of the rack 70 may be correspondingly shortened and lengthened, as is obvious. The gear wheel 79 is mounted upon a shaft 80 which extends transversely of the press and is journaled in suitable hearings in the side frames 30 and 31. Power is transmitted from the main driving shaft 81 to the gear wheel 79 by a car train including driving pinion 82 meshmg with gear wheel 83 upon a shaft 84, and pinion 85 upon said latter shaft meshing with gear wheel 79. This gearing is so proportioned that the gear wheel 79 makes one revolution for each impression, or, in other words, one revolution for each to-and-fro movement of the type bed. As the wheel 79 is clearly illustrated in Fig. 21. shown, the arm 87 is made integral with rotates, the segment 7 5 is oscillated and the racks 70 and 73 reciprocatedwith corresponding forward and backward rotations of the gear wheel 68 and consequent step-bystep advancesof the fountain roller 43.

Referring to the fountain duct roller 42 and its actuating mechanism, it will be seen that said roller is journaled in the outer ends of arms 86- and 87, whichv are respectively pivoted to the side frames 30 and 31 or suitable extensions of said frames. The connection of the arm 87 to the side frame As there arms 88, 89 and 90, and are formed on a common hub 91 keyed to a shaft or spindle 92 which constitutes the pivotal connection of these arms to the side frame 31. The connection of the arm .86 to the side frame 30 is a simple pivotal connection. The outer end of the arm 89 is pivotally connected to the upper end of a vertical rod 93 which passes through guiding openings in flanges 94 and 95 of the transverse frame member 32. This rod carries acollar 96 which is secured to it by a set screw 97. This collar forms the upper abutment of a coiled spring 98 which is coiled about the rod 93 and bears at its lower end against the upper face of the flange 95. The collar 96 may be shifted to vary the compression of the spring to increase or decrease its upward action upon the rod 93. This action tends to normally hold the fountain duct roller 42 against the fountain roller 43. In order to move the roller 42 out of such engagement and in opposition to the action of the spring 98, the

99 which is loosely mounted on the spindle and which is in position to engage a portion of the arm 88. The arm 99 is moved to and fro by a rod 100. As the rod moves in one direction, the shoulder 101 on the arm 99 engages the end of the screw 102 extending through the outer end of the arm 88 and forces the arm 88 and its connected arm 87 in a direction to raise the fountain duct roller 42 out of engagement with the fountain roller and to bring it into position to engage the ink plate 40 and the roller 44. By turning the screw 102 which is threaded through the arm 88 and holding it in place by the locknut 103, a nice adjustment may be obtained between the parts. As the rod 100 moves in the opposite direction, the spring 98 acts through the rod' 93 and the arm 89 to bring the roller 42 into engagement with the fountain roller 43. This return movement is limited by the engagement of a screw 104, similar to screw 102 and having a locknut 103*, which passes through a threaded by a bell crank lever 106 to one arm of which it issecured. The bell crank lever 106 is pivoted at 107 and the other arm is provided with a cam roller 108 which rides upon a cam 109 mounted upon the shaft 80. This cam is of the proper shape to give the parts the desired reciprocating movements. I

Referring to the ink plate rollers it will be seen that the journals of each are mounted in suitable bearings carried at the one end upon a frame 111 and at the other upon a frame 112, the latter of which is vertically movable with reference to the main frame of the machine. One of these bearings, designated 110, is illustrated in detail in Figs. 14 and 15., As there shown, the bearing has a slot-like depression 113 formed between the upward extending portions 114 and 115. The bottom of thedepression 113 forms a bearing for the journal of the roller. To properly lubricate, the bearing surface, an oil groove 116 is provided. An oil duct 117 connects the oil groove 116 with an oil well 118 formed in the body of the upward extension 114. For the purpose of raising the rollers out of their normal operative engaging position, the bearing 110 is provided with an arcuate clip 119 which is pivoted upon a screw 120, which is threaded at 121 into the body of the bearing. This screw is surrounded by a coiledspring 122 which is turned at one end into an opening in the body of the bearing and at the other end into an opening in the hub 123 of the clip 119. The spring 122 normally yieldingly holds the clip 119 in engagement with the stop pin 124 upon the upward extension 115. A projection 125 on the clip 119 serves as a fingerhold by which the clip may-be readily moved by hand out of its position against the stop 124 for the purpose of raising the journal of the roller out of its normal bearing, or of lowering it into such bearing. The upper portion of the clip is cut awa as shown at 126, to form a seat or bearing or the journal of the roller when in its non-service position. The under face of the hooked portion of the clip fits over the top of the roller journal to hold the roller from jumping up when it is reversing or rolling over the ink plate. The lower portion of the bearing 110 terminates I in a pin 127 which rests in a socket 128 and is'held in adjusted position by a set screw 129. A suitable opening 130 in the socket 128 enables the bearing to be secured in position upon its supporting frame. This socket member 128.'is of course made of d1fferent shapes andfdimenslons to suit the character and location of the roller with nated'47and 50. Where rollers which are nearer to the ink plate are to besupported, the socket members are shaped as shown at 132 and133.

In the arrangement of plate inking rollers shown, the steel rollers 47 and 50 are positively driven through gearing. For this purpose the spindle of the roller 47 is provided with a gear wheel 134 and the spindle of the roller 50 is provided with asimilar gear wheel 135. are on rider vibrator rollers, they are made somewhat 'wider than. the gear wheels 136 and 137 with which they respectively mesh. These latter gear wheels mesh with gear Since these gear wheels I wheels 138 and 139, respectively,,and gear wheels 138 and 139 mesh with a gear wheel 140 which in turn meshes with a gear wheel 141 mounted upon the same spindle as the sprocket wheel 142.- The gear wheels 136, 137, 138 and 139, are mounted on spindles which are secured to the frame 111. The gear wheels 140 and 141 are mountedon spindles which are secured to the main side frame 30. The sprocket wheel 142 cooper-.

ates with a second sprocket wheel 143 located on the opposite side of the impression.

cylinder 39 from it and serving as an idler wheel for the I sprocket chain 144 which passes over both of said sprocket wheels and is secured to a plate 145 which is fixed to the bed 34 bybolts or other suitable and forth. 1

Referring to the form inkingrollers, the same have their spindles mounted in bearings 147 and 148, which are similar in construction to the bearings 110 but are not provided with clips. These bearings147 and 148 are secured to extensions of the main frame located respectively on the gear-' ing and feed sides of the press; The form duct roller 53 has its spindle mounted in bearings 149 and 150 upon the outer ends of thepivoted arms 151 and 152, respectively. These arms are keyed or pinned to a transverse shaft 1'53 which is suitably journaled in bearings 154 and 155 located upon theframe structure at opposite sides of the press. The shaft 153 also has keyed or pinned to' it a pair of arms 156 and 157 which carry cam rollers 158 and 159 at their outer ends. These cam rollers ride upon the bed 34 as it reciprocates. As they travel along their path upon the bed, the cam roller 158 encounters a depression 161 and the cam roller 159 encounters a depression 160. Whenthese depressions are encountered the duct roller 53 is lowered and because of the locations of these depressions it is lowered into engagement with ,theink plate. When memes the point is reached at which the duct roller 53 is to leave the ink plate, the cam rollers 158 and 159 pass to the normal face of the bed again and thereby raise the duct roller up, into engagement with the associated ink distributing roller 56. In this way upon each reciprocation of the bed 34 the duct roller 53 takes up ink from the ink plate and transfers it to the associated roller 56. By varying the length and position of the cam depressions 160 and 161, ink may be taken up by the form duct roller from any desired portion of the ink plate and the bal v ance left for the form inking rollers 54 and 56 which also engage the ink plate in its reciprocations. V

The form distributing rollers 56,57, 58,

.59 and 60 have their-spindles mounted in bearings in a movable frame consisting of the side members 162 and 163 which are connected by rods 164 and 165. These side frames are" connected to the main frame by links, the links 166 and 167 connecting side member 162, and the links 168, and 169 connecting the side member 163. The distributing roller frame may be moved upon its links so as to raise the distributing rollers up out of engagement with the associated form rollers and the form duct roller, and thereby leave all the rollers readily avail- .able for inspection and repair. In order to raise the distributing roller frame, the link 169 has a segment 17 0 secured so as to rotate with it about its pivot. 1 This segment is provided with Worm teeth so as to cotiperate with a worm 171 mounted upon a suitably journaledshaft 172 which is actuated from a hand wheel 17 3 through bevel gear wheels 174 and 175. As the hand wheel 17 3 is rotated, the link 1 67 raises the distributing roller frame from the position shown in Fig. 6 to that shown in Fig. 8'.

Two ofv the form distributing rollers,

namely,those designated 56 and 60, are positively rotated through the agency of rack 170, pinions 171 and 172 meshing with.

said rack and driving gear wheels 173 and 174 on the spindles of said rollers, respec- .tively. The rack 170 is mounted upon the.

bed 34 and moves with it. The pinions 171 and 172 are mounted on spindles projecting from extensions 17 5 of the main frame. In operation the oscillating movements of the rack 17 0' are transformed into rotary movements of the rollers 56 and 60.

As the form distributing. rollers are raised in response to the operation of the hand wheel 17 3, the spindlesof the rollers 57 and 59 are raised at one end so as to lift the rollers out of engagement with their companion composition rollers 56, 58 and 60. This is brought about by providing a bar 176 to engage the under side of'the spindles as the dlstributing .rollerframe is being elevated, The bar 176 normally lies which is fixed to the main frame.

far enough below the spindles to allow the rollers 57.and 59 to properly engage their companion rollers but when the parts are utilized to raise the. spindles of the form inking rollers 54 and 55 at one end so as to lift these. rollers clear of the form and the inking plate in case the bed should be reciprocated. For this purpose a plate 179 is arranged to slide upon an extension 180 Screws 181 extending through a slot in the member 180, serve to guide the plate 179 in its up-and-down movements. has a cam-engaging portion 182 at its lower end which cotiperates with a cam 183 which is pivoted to a fixed portion of the frame at 184. The cam 183 is moved by a connecting rod 185, which is in'turn connected to a crank arm 186 mounted upon the same spindleas the gear segment 170 and so as to rotate with it. As the segment is rotated, the cam 183 raises and lowers the plate 179 with a corresponding raising and lowering of the spindles of the form inking rollers 54 and 55. Thus we see that by operating the hand wheel 173 the form distributing rollers may be elevated into a sultable position for inspection and repair or replacement of rollers and at the same time the various rollers are moved out of engagement with each other so as to prevent their deformation.

As before pointed out, rollers 47, 50, 56

and 60 are vibrator rollers, and the first two are actuated from the rock-shaft52, andthe latter two from the rock-shaft 61. The spindles of these rollers are provided with extensions 189 from the upper ends of cross arms 190 and 191 located upon the upper ends of the rock-shafts52 and 61,-

respectively. As these shafts are rocked, their armsl90 and 191 are likewise rocked .to give a reciprocating movement to the vibrator rollers. The shafts 52 and 61 are suitably mounted in brackets on the side and in the form shown lies directly be-n neath the arm 196. As the arm 196 is The plate 179' ,with collars 187 and 188 for coiiperation- I moved back and forth its movements are transmitted through the rod 195 and arm 194 to rock-shaft 52. As arm 197 is moved back and forth, its movements are transmitrock-shaft 201 is provided with an arm 203 whichhas a cam roller 204 extending downward from its outer end into the cam groove of a cam 205 keyed to the transverse shaft 80. As the latter is rotated, the cam 205 moves the arm 203 back and forth so as to rock the shaft 201 and the head 198 with its arms 199 and 20.0. The connections of the arms 196 and 197 with the arms of the head 198, are adjustable so as to vary the extent of the oscillating movements of the shafts 62 and 51. This adjustment may be made to vary from zero to a maximum in each instance by shifting the connecting bolts 206 and 207. Where these bolts are in line with the rock-shaft 201, no oscillation is produced. As they are moved away from this position oscillation begins and continues to increase according to the extent of the movement. By being able to reduce the oscillation in this way tozero, I am enabled to print with two colors of ink without having the colors overlap or intermingle. As clearly shown in Fig. 12, the bolt 206 passes through a slot in the arm 196 and by means of the washer 208, shoulder 209 and nut 210, may be securely fixed in position upon the arm 196. It is provided at its lower end with an anti-friction roller 211 which engages the walls of the groove in the arm 199 of the head 198. The bolt 207 has the same parts and they are similarly arranged with reference to the arms 197 and 200.

In addition to moving the ink plate roll-- up high enough so as to clear the ink plate in its reciprocations. I accomplish this by raising the plate 112 by means of cam levers 212 and 213 which are pivoted near their upper ends to a fixed portion of the frame and are connected at their lower ends to a longitudinally movable rod 214. The upper end of each of these levers 212 and 213 is provided with a cam face 215, asclearly shown in Fig. 20, which operates against a pin 216 extending laterally from the movable frame 212 into the path of movement of the cam 215. The pins 216 extend through the frame plate 112. Their inner the cam levers 212 and 213 and their outer ends ride up and down in guiding slots formed in projections 212 and 213 of the main frame structure. As the rod 214 is moved from the position shown in Figs, 1 and 20, the cams 215 upon the levers 212 and 213 engage their respective pins and raise the frame ,112 and thereby raise one end of each of the several ink plate rollers. It will be noted that the gearing by which the rider vibrator rollers 47 and 50 are rotated is at the opposite side of the machine and therefore that the cotiperating wheels will not be thrown out of mesh.

In addition to performing this function, I provide a projection 217 upon the cam lever 213 which is adapted to engage the arm 90 to raise the fountain duct roller slightly out of engagement with the fountain roller whenever the ink plate rollers are elevated at one end. It will be. seen tion 217, the fountain duct arms' 86 and 87 will also be raised because arm 90 is integral with arm 87, and consequently the fountain duct roller 42 will be raised out of engagement with the fountain roller 43.

In addition to raising these several rollers out of operative position, I provide a cam lever 218 for raising the form duct roller 53 out of ink plate engaging position. As shown more clearly in Fig. 5, the cam lever 218 engages a pin 219 which extends laterally from the arm 152 at a point directly beneath the bearing 150. As this cam lever is oscillated, the'outer end of the arm 152 is raised and lowered with a corresponding movement of the form duct roller 53. The cam lever 218 is connected at its lower end like the cam levers 212 and 213 to the reciprocating rod 214, which is offset so as to give a proper degree of movement to the cam lever 218.

The operation of the rod 214 to actuate the cam levers 212, 213 and 218, is brought about by a pedal 220 extending. through a footboard 221 located at the feed side of the press. The lower end of the pedal rod 222 is connected to an arm 223 which is mounted upon and'secured to a sleeve 224 surrounding a transverse rock-shaft 225. The end of the sleeve 224 adjacent to'the gearing side of the machine is connected to a crank arm 226, and the upper end of this arm is connected tothe end of rod 214. As the" pedal 220 is 'moved up and down, the rod 214 is moved back and forth'to actuate the cam levers to move the .parts as just explained. A spring 227 connected at one end to'the arm 223 and at the other end to the footboard 221, yieldingly holds neaaeee footboard 221 to hold the pedal in depressed position. This result is accomplished by moving the pin down through the wide portion of the slot and then rocking the pedal about its pivotal connection with arm 223 to bring the pedal into the narrower. portion of the slot 229 with the pin 228 beneath the adjacent overhanging portions of the footboard 221.

The impression cylinder 39 is driven from the main drive shaft 81 by means of the drive pinion 82 meshing with gear wheel 230 which in turn meshes with gear wheel 231 carried upon the impression cylinder. The impression mechanism of the press includes eccentrics 232 and 233 mounted in the journal boxes 37 and 38- and frame eX- tensions 35 and 36, respectively, both eccentrics being operated from a rock-shaft 234, the former by crank arms 235 and 236 connected by a rod 237, and the latter by crank arms 238 and 239 connected by a rod 240. The requisite oscillations are given to the rock-shaft 234 by means of a pin 241 mounted at the end of an arm 242 upon shaft 234, and a coiiperating latch 243 carried at the outer endof an oscillating arm 244, which is actuated by a cam roller 245 working in a cam groove 246 upon the inner face of the gear wheel 79. As the latter rotates, the

latch is moved back and forth and the cyl- 'and 250 are oscillated about their pivotal inder is given its roper impression movements. An arm 24 is secured to the end of rock-shaft 225' and the latter is provided with an arm 248 which is connected to the lower end of the rod 249 of the pedal 250. By depressing this pedal, the shaft 225 is rocked and the arm 247 is raised. This arm is provided with a groove on its inner face and the upper and lower walls of the groove cooperate with a pin 251 which extends laterally from the latch 243. As the arm 247 is raised it lifts'the latch. 243 so that the pin 241 will pass outof its normal engaging position in the slot or notch in the latch. As the latch 243 moves to the right, as Viewed in Fig. 1, the long point at the forward end of: it will still engage the pin 241 and bring it into position to raise the impression cylinder. In other words, itwill draw the pin 241 as far as the latch 243 moves toward the right, and thus raise the cylinder to clearance position. Upon the return movement of the latch, however, thepin 241 will not be engaged to cause the impression cylinder to be lowered, but the latch 243 willr-ide' freely over the pin 241 and the cylinder will be left in its elevated position. In this way the impression cylinder is always raised-to its clearance position no matter when the impression mechanism may be tripped. As long as the arm 247 holds the latch 243 in its elevated position, the pin 241, after once being moved to its right hand position as viewed in Fig. 1,

will remain there until the arm 247 allows the latch 243 to again fall so as to allow its slot to engage the pin 241. As clearly illustrated, the springs 253 and 254 operate between projections upon the upright portions 35 and 36 of the main frame and projecting shoulders upon the. cylinder journal boxes. Their function is' to counterbalance the weight of the cylinder and the parts which move with it. This cylinder tripping mech anism allows the impression mechanism to be thrown out of, action and thereupon leaves the cylinder elevated so that the bed may be reciprocated without its coperating action. In this way the form may be inked without producing an operation of the im-- pression cylinder. This impression mechanism is similar to that disclosed in the patent to Miehle No. 550,992, granted December 10,1895, and in itself forms no part of the present invention. 1 have, however, provided an interlocking member 255 by which the pressing of the single pedal 250 will not only actuate cam levers 212, 213 and 218, to raise the rollers in the way described, but also trip the impression mechanism so as to leave the cylinder in its elevated position. This interlocking member 255 is provided with a forked lower end 256 which straddles the pedal rod 249 so that no matter. to what extent the pedals220 connections withtheir arms 223 and 248, the forked end will still engage the rod 249. The upper end of the interlocking member 256 is provided with a lip or shoulder 257 which is adapted to engage the lower edge of the pedal 250, but which may be thrown out of engagement with it by oscillatin the pedal 220 into the left-hand portion of the lit described in connection with pedal 220.

When the shoulder 257 is out of engagement with the pedal 250, then the latter may be, operated without actuating pedal 220. On the other hand, even thoughshoulder 257 is in position to be engaged by pedal 250, yet pedal 220 may be operated without in any way operating pedal 250. When the shoulder 257 is in position to be engaged by pedal 250, which is the position shown in Fig. 1, the act'of pressing upon the pedal 250 trips? the fountain. duct roller 42, the form duct roller 53 and the impression cylinder. When the shoulder 257 is not in position to be engaged by the pedal 250, the

act of pressing down the latter has no further function than to trip'the cylinder. In this connection it may also be pointed out thatwhen the rod 214 is actuated as a result of pressing down the cylinder trip pedal 250, the roller frame 112 is not raised by the associated cam levers 212 and 213 because the movement of the rod 214 is insufficient for this purpose, although suflicie'nt to actuate the duct rollers and 53, as before stated. If it is desired toraisethe roller frame 212, it is necessary to furtherdepre'ss the pedal 220 and to hold it in locked position when thus depressed. Thus the actuation of pedal 220 by direct applicationof the foot gives a greater movement of the rod 214 than is given by de-pressing'the cylindertrip pedal 250 by the foot.

In Fig. 2 I have iilustrated in diagram a modified arrangement of form rollers in which there are three form inking rollers 262, a single form duct roller 263, and five inkv distributing rollers designated 264 and 265.

In this modification the rollers 265 are steel rollers and the others composition rollers.

In this diagram the imp-ression'cylinder is designated 266. From the previousdescription it will be'readily understood how these various rollers are. to be mounted and operated.

It is clear that inca' r ing out-my invention other numbers. an 5 arrangements of form inking and other rollers may be em-f comprising form inklng' rollers, associated ployed just as well'as-the number and arrangement herein disclosed, Likewise,

. many other alterations "and modifications may be made in thearrangements and details of the parts without departing from the s irit' and scope of my invention.
